Report #81791

[architecture] Centralized orchestrator agent becomes a latency bottleneck and single point of failure as the number of worker agents scales

Shift from a centralized 'star' orchestration to a hierarchical or peer-to-peer delegation model where worker agents can directly delegate sub-tasks to other workers without routing through the root orchestrator.

Journey Context:
A top-down orchestrator is easy to implement and debug but doesn't scale. The root agent's context window gets flooded with summaries from all workers, and its rate-limit dictates the system's max throughput. Hierarchical delegation \(e.g., a 'Manager' agent delegating to 'Lead' agents who delegate to 'Worker' agents\) distributes the routing logic and context management, preserving the root's context for high-level goals.
